Thanks for the info man, I appreciate it. But what does 4x4 mean? Most of the sizes I see are giving the dimension in mm like 4X 100, 4X110 and so on.
Now 4" converted to mm is actually 101.6 (Im not really that smart I just google it

) so I am assuming I would need the 4X100?
Never mind I just found the 4on4 as they call it. I do appreciate the quick responses. I need to get this thing ready for the dunes on Presidents Day
Do you know who makes a 6 paddles tire as all I can find now is 8?
